Large object flying in sky silently

I just arrived home and was getting my key ready for my front door. I spotted a very large light in the distance to my right that was very bright white and very big. My first thought was it was a planet, but I noticed it growing in size and getting closer. It was too low in the horizon to be outside the atmosphere. I watched as it got closer and the large white light began to separate into two large white lights with two bright blue lights flashing below them. It was completely silent and was moving moderately fast; it wasn't so fast it was a blur but it crossed the sky and was out of sight in only two or three minutes. There was no engine, propeller, or even any turbulence noises. I couldn't make out wings or a defined body and could only see the lights as it passed overhead. Judging from the distance between the lights it was the size of a commercial jet but flying way too low. It wasn't a Starlink satellite as it was clearly flying below the clouds as when it got in the distance it was flying below the line of the red flashing lights from the windmills. It was greatly too big to be a drone and the lights seemed to be fixed to something as they moved in unison and without lagging individually at all. The large white lights looks like they had to be feet across in diameter and appeared spherical. The blue flashing lights were much smaller than the white lights but were also piercing bright.
